Bass String Suggestions/Options/Possibilities

Hi. I'm new to the bass guitar but have played six string guitar for years. Interested in Blues, Classic Rock, Hard Rock & Rockabilly music. Never played bass before.

Just purchased a five string Schecter Damien-5 bass guitar with two EMG-40hz pickups and a 35" scale. I believe the five string bass guitar will arrive tuned to BEADG.

What's the advantage to BEADG?

I'm thinking of tuning to "one octave below" the six string guitar's tuning to EADGB(E). Is there a problem for this as a bass player? Since I'm a guitar player, it seems EADGB(e) would be easy to follow watching or playing bass with other guitarists. I know I'd need to get proper strings and have them intonated correctly.
